The aim of this study was to compare the Query-by-Humming systems Midomi, Musicline and Tunebot regarding their retrieval effectiveness. The aim was to see if there were differences between the systems but also between the user groups common users, musicians and singers. Query-by-Humming system means that the user sings a tune that the system then use to find the right melody.To compare the systems and their users, queries where collected from the different user groups and replayed for the systems. Mean Reciprocal Rank and Friedman test was used to do the comparison.The results showed that the system did not achieve equivalent and that there were no difference between the user groups. The Mean Reciprocal Rank showed that the systems had very different retrieval effectiveness, where Midomi was the system with best result and Musicline with the lowest result..

This thesis examines which function the information technology may have in thechildren's library, with the example from two library computer programmes. One is anexpert system, Hedvig, which will help children to choose and to find books, and theother is a computer game, The mysterious signs, that will teach children library user education.The main question is: What conceptions do the project-leaders, the children'slibrarians and the children have concerning the function of these two programmes in thechildren's library?The study is based upon qualitative interviews with two projects-leaders, fourlibrarians, three computer programmers and twenty-eight children.The theoretical material consists of examples on other library computer programmesfor children developed in Denmark and USA, some American studies in children'sabilities to use computerized information retrieval systems, and studies concerningchildren's relations to computers.The adult's conceptions of the computer programmes are divided into categories asfollows: Democracy, aspect of sex, complement, marketing, reading promotion,development of competence, information technology development, pedagogics, adulteducational activities, compensation and armusement, pedagogics, usefulness,effectiveness and information. These categories shall be seen as the conclusions of the thesis..

Den amerikanske flygvapenöversten John A Warden III har lagt fram en teori om att man kan se på fienden som ett system av system för att hitta hans svagheter. Teorin bygger på att skapa en bild av fienden genom en fördefinierad indelning i subsystem bestående av fem ringar. Denna bild skall därefter kunna brytas ner i ytterligare subsystem bestående av samma fem ringar som till slut avslöjar fiendens tyngdpunkter. Uppsatsen prövar om Wardens teori går att applicera på Al-Qaida..

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

AbstractThis study investigates the impact of storytelling for children's language development in preschool from a sociocultural perspective. The purpose is to find what narrative methods teachers use to promote children's language development. I also want to examine whether the children are involved in the storytelling. To get answers to my questions which include what methods teachers use, narrative meaning and function, and their children's participation, I have used qualitative interviews with four preschool teachers at four different preschools.The results of my survey show that teachers use a variety of methods at storytelling. The most common methods were reading, rhymes and daily storytelling while eating.

This study is an attempt to investigate religious perceptions and its development, function and connection to religious practise within the Swedish extreme metal scene. This is performed mainly by a qualitative method of investigation, studying lyrical content published on a number of extreme metal albums, thereafter relating the lyrical progression to the progession of the scene as a whole and also to the development of individual religious belief and practise.The lyrically expressed manifestations of religiosity within the extreme metal scene prove to be related to religious practise in some cases, most visibly in the Christian parts of the scene.The study also indicates that development of religious expression often is evident regardless of religious preference. This development also regularly relates to an increase in musical evolution and prowess often achieved with increased age and maturity.Musically and lyrically, the extreme metal scene displays transgressive attributes which assist both individual and group in the process of creating identity, meaning and individuality.Experiencing extreme metal, in concert or in the privacy of one´s own home, can be one way of perceiving spirituality in this modern age..

The aim of this Master thesis is to investigate the similarities and differences between a traditional and a new classification scheme. Two classification systems are compared, "The Swedish Library Classification System" the SAB-system - and Yahoo!. The SAB-system has been used in Swedish libraries since the beginning of the 20^th century, and Yahoo! has been online since 1994. Yahoo! has a Swedish version of its international original, which is used in this study to get a similar starting point with the SAB-system. The method used for this is a content analysis, which in this case is not a quantitative analysis.

Detta arbete tar upp iden om att datorspel kan användas som ett hjälpmedel för att förstå och hantera komplexa system, för den enskilde spelaren såväl som för forskare. Arbetet fokuserar på ett antal kritiska faktorer: möjligheter, problem och frågeställningar, samt tar upp en diskussion kring möjligheten att se datorspel som världar, lika verkliga som vår egen, då vi ser på det från en position innanför systemet, genom speljaget som en agent i den virtuella världen, och vilka implikationer detta kan få för hur vi kan lära oss att förstå och hantera komplexa system.Vi lever i en verklighet i vilken vi omges av komplexa system, både sådana vi skapat själva och sådana som finns naturligt. Det är en paradox att den teknologiska utvecklingen som strävar efter att förenkla vår tillvaro också undantagslöst komplicerar den. Att försöka hitta nya vägar att kunna lära oss att förstå och hantera dessa komplexa system är därför viktigt, och här presenteras datorspelet som ett tänkbart redskap för att göra just detta..

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

The purpose of my report was to find out how music can benefit the language development of children, whilst getting a glimpse of how the educators in preschools use music as a tool for the language development of children. During the course of the report I?ve used the sociocultural perspective theory as a foundation to stand on, this is most of all visible in my analysis and discussion of the result. In the result we can see that the educators possess insight in the importance of music in childrens development, and that they therefore give music a lot of room in their work. Songs where rhyme and language play are allowed are common elements at the preschool that attracts the children and makes them want to partake. Songs sung with movement is a commonly used combination which also serves to further lift the childrens language development when they, through movement, give meaning to the lyrics. It does however take a devoted educator to make music with the preschool children and to support them and making them want to do it.

In order for companies to be competitive they perform different types of development projects.  Due to globalization a greater focus is added on costs, not least on costs in development projects. Project controllers are involved in development projects in order to review the financial aspects. The authors have examined the role that project controllers hold in respect of two Swedish manufacturers, Volvo CE and Scania CV. The investigation has revolved around three main issues where the authors conducted interviews with controllers that do not work in development projects and project controllers in development projects. The goal of the interviews was to gain a greater understanding of the role of project controllers, how this role will differ from those that do not work in development projects and the difficulties faced by project controllers.

The purpose of this study was to examine how teachers practice Arne Tragetons theory of using computers as the first writing instrument in reading and writing development. We wanted to clarify how the work from using Tragetons theory was applied while investigating if and how other methods of reading and writing instruction were used. Our interest lays in how the teachers accomplished the knowledge of this theory and also how the choice of this approach came about. To investigate this we used interviews with a qualitative nature, where seven active teachers were interviewed. They worked in three different schools in years one to three, they were all women and had various long experiences of work on the computer writing tools.

 This report is an evaluation of Peab's purchase and call-off system, PIA.PIA is used to order goods for Peab's construction sites. The background to the work is that users of the system have understood the system cumbersome to use when purchasing goods for construction sites. The evaluation was carried out by the interviews and tests with users of the program, in this case, supervisors and site managers at the company. Ten users of the system were interviewed and eleven people have carried out a test order.The focus is primarily on the test order that users have implemented, which has been clocked and analyzed for time and cost. The evaluation is also a user analysis concerning how the users perceive the program, mainly in terms of usability, functionality and benefits.The result of this report shows that PIA is economically profitable to use for the purchase of goods for construction sites.
